ABSTRACT:
A level sensing device for household appliances or the like. The device comprises a compartment (25) which at its lower part via a single combined inlet and outlet (42) is connected to a treatment chamber into which liquid is supplied. The upper part of the compartment (25) is divided into two sections (26, 27), one section (26) communicating with a pressure sensing means and the other section (27) communicating with atmosphere. By this arrangement a rapid and complete emptying of the sensor is ensured when the treatment chamber is emptied.
